To @ZZ whom t may concern:

-Be it known that I, CHESTER S. KING, a citizen of theUnitedStates,residin g at Smethport,

in the county of McKean and Stateof Penn# Sylvania, have inventedcertain new and useful Improvements in GasRegulat-ors, of which thefollowing is a description.

The figure is avertical longitudinal section.

Numerous forms of gas regulators have heretofore been patented whichwere designed to render the iiowof gas uniform in its passage from themains of the street tothe distributingpipes of a building. Theregulation of the iiow of artificial gas is not particularly difficult,for the reason that its variations of pressure are but slight. When,however, the ordinary forms of regulators are applied to the regulationof the flow of natural gas as it comes from the oil-wells and isdistributed to the buildings, the usual forms of `regulators areYinsufficient, for the reason that the pressure of the gas varies from afew ounces to as much as twenty pounds by reason of variation inconsumption and flow, and this, when the pressure is suddenly increased,causes the valves of the regulators to shut and stay shut from the greatpressure of the gas. My invention provides a means for preventing thiscontingency, which means effect a perfect bala'ncingof the valve for allpressures, as hereinafter fully described.

In the drawing, A represents the inlet and B the outlet pipe frommyregulator. The inlet-pipeA leads into a box-like chamber,0, which hasa cover, D, and a cap, E, and between which cover and the chamber isclamped a substantial diaphragm, F, of rubber or other iiexible materialby bolts a. The chamber C communicates by a short pipe, b, with thelower chamber of a three-compartment chamber, G G G2, composed of threesections bolted together by bolts c. The lower chambers G G areseparated by a rigid horizontal partition, H, having in its center anopening, d, through it, forming a valve-seat. Between the iianges of theupper chambers G G2 is secured a iiexible diaphragm, I, which isattached to a central stem, J, bearing valve J by screw-threadedclamp-disks K, the stem extending through the hole in partition H, andthe valve being affixed to the stem below the said partition. Upon thechamber C is (No model.)

mounted a standard, L, to which is fulcrumed, at e, a horizontal lever,M, which lever is jointed to the upper end of' valve-stem J, and bearsan adjustable weight, N, on one side of the fulcrum, and on the otherside of the fulcrum is j ointed to astem,0,that passes through aeap onlchamber G and isV connected by a screw-thread to the clamp-disks P,which attach it to the diaphragm F.

Now, in the operation of the valve J', diaphragm I, and two chambers, GG', when the gas passing up throughhole d exceeds in pressure thenormal, this pressure, acting against diaphragm I, raises the same andwith it raises valve J and Acorrespondingly closes the hole d,diminishing the iiow of gas eseaping through pipe B to the burners.4When, however, the pressure in G and the pipe B falls below the normal,the diaphragm I in falling opens the valve J and increases the iiow.

As so far described, my invention works upon phragm F, stem O, and leverM, for when the pressure is increased the lifting action of diaphragm Fby the reverse action of lever M produces a downward pressure on thevalve J', that 'holds it always in perfect balance for It is essentialfor all variations of pressure. the most sensitive action, however, thatthe area of the diaphragm F should bear a certain definite relation tothatof the lower side of valve J-i. e., if the fulcruin e of lever Mshould be exactly half-way between the valve J and diaphragm F, then thearea of the diaphragm F and valve J must be equal, in order to balance.If, however, the diaphragm F is larger than the valve J, as Iprefer it,and as is shown, then the fulcrum-pointe of the lever must be moved asmuch nearer the diaphragm as the latter is larger in area than thevalve, so as to preserve always a perfect bal- IOO ance. This preventsthe variation of pressure from permanently closing the valve, and yetallows the latter to have a sensitive automatic movement from the actionof the other and larger diaphragm, I.

In fastening the chambers G G G2 together, the bolts c do not passthrough holes, but through open slots c2 in the flanges of these parts,which permit the bolts to be loosened and taken out sidewise; and theseslots are all the Same distance apart, so that the chamber G may beturned around and bolted in any position in order to bring theoutlet-pipe B into the proper relation to the pipe of the house.

To open or close the opening d more or less, the stem J may bedisconnected from the lever and screwed up or down through the disks KK, and the weight N may be adjusted to put more or less downwardpressure on the valve.

Having thus described my invention, what I claim as new isl. Thecombination, with a gas-regulator consisting of a suspended valve, avalve-stein, a diaphragm, and a valve-seat located above the valve, of aseparate diaphragm arranged nearer the source of supply than the valve,and an external lever connected to both this diaphragm and the valve, tobalance the latter against variations of pressure, substantially asshown and described.

2. The chambers G G G, having flanges at their edges, with open slots inthe same at regularintcrvals, in combination with bolts c, diaphragm I,the valve, valve-stem, and valveseat, as and for the purpose described.

3. The combination of the chamber C, pipe b, the connected chambers G GG2, with perforated partition II and diaphragm I, valve and valve-stein.I J', lever M, standard L, stem O, and diaphragm F, as and for thepurpose described.

The above specification of my invention signed by me in the presence oftwo subscribing witnesses.
